Best Gaming Rig for $700 Max

[ghost101]

I am looking to get the best gaming computer possible. I do not care what parts I will use at this point, AMD, Intel, etc. I just want to most optimal performance for my money. You guys helped me decide to build my own over buying a prebuilt, which is a good start I think! Now I just need a build that will allow me the most power for the cost. I PREFER a build that is around $650 but I can push it to $700 if the extra $50 makes a large difference. Please post a build that will allow me the best performace for the money. And if you dont mind, let me know what games it can handle that are higher end, like Skyrim, Call of Duty, Mass Effect, etc. I will be buying the parts for the computer today, and prefer to get them from Amazon if possible.

Thank You all for those who took the time to help me out, I greatly appreciate all help! You guys are great!

Does the $650-700 budget include OS, monitor and peripheral?

I need an operation system, windows 7. I need no keyboard or mouse and no headset etc. I assumed an operating system would be part of the build...
